Good starter amp recommendation


Was lurking for a while, decided to post.

I have an old system with Energy RC-30 speakers and currently using a Denon x3400h to drive them. The system is used mostly 80/20 for music/movies, and uses an Energy RC-LCR center for movies.

Would like to add a simple 2/3 channel amp for around $1000 to improve the sound and was looking at some more recommendations. Want it to be a good part of the system, but since the speakers are pretty basic, don't look for anything too fancy, but good enough to upgrade the speakers later on.

Looking around the forum, the following is my short list:
van Alstine SET 120 or Synergy 240/3
Odyssey Khartago (or used Stratos)
Anthem PVA or MCA (used is all I can afford, probably)
Parasound A23

Would like to hear any suggestions.

My comment on the B&K ST 140, was stated by me " by todays standards ". Yes, I agree, back then it was a good amplifier, and especially for the price. But not today, and this, is ime, and, imo. Sorry to have hurt some feelings here. But even back then, there were many competing amplifiers that did not sound the way I described, as this is how I remembered them sounding. I sold them, and liked the ex 442 and Pro 600. But the ST 140 was good with small bookshelf type speakers, and if anyone thought they were lucky, well, that would not be my take on it. Let me move on.

I can speak to 2 components mentioned here, the NAD C326 BEE and the Nuforce STA-200. I own both and the Nuforce is by far the more articulate sounding amp. After listening to the NAD for so long it was like someone lifted a blanket over my speakers. Combine the Nuforce with a Schiit Saga and you’ll be surprised by the sound for the money!
The NAD is an integrated amp and the Nuforce is only a power amp. Going from an integrated to a separate pre/power opens up a whole new discussion.
The OP is currently using a Denon AVR receiver. I don't know if the Denon has pre-out capability to enable use of a separate power amp and if the OP has that intention? Or, to completely replace the Denon?
